Whittier Narrows Operable Unit Treatment for Drinking Water End Use Project
MND - Mitigated Negative Declaration

The project would construct a new 7,265-foot-long blend water supply pipeline, a new 20-foot-long blended water pipeline connection to the existing 30-inch San Gabriel Valley Water Company (San Gabriel) pipeline on Durfee Avenue, and a new off-site booster station (Plant B28 Booster Station). The implementation of the proposed project would provide additional water for blending with groundwater produced from the existing WNOU extraction wells, as well as boosting capacity to deliver this blended water to San Gabriel for distribution to its customers.
The purpose of the proposed project is to increase the pumping rate of the existing groundwater extraction wells to contain groundwater contamination within the Main San Gabriel Basin. The project would increase the capture of the contaminants and prevent further migration into the adjoining Los Angeles Central Groundwater Basin (Central Basin) and help protect nearby municipal water supply wells.
